Definitions
- the present invention relates to an electrical connector, and more particularly to an electrical connector for a sheet-like connection member such as a flexible printed circuit or cable (FPC), a flexible flat cable (FFC) and so forth. All of these cables and circuit will be generally referred to as “FPC”.
- FPC flexible printed circuit or cable
- FFC flexible flat cable
- a conventional FPC connectors generally includes an insulating housing defining a cavity opened to a front face thereof, a plurality of terminals loaded in the housing and extending into the cavity, and an actuator assembled to the housing and movable between an open position and a close position relative to the housing.
- the actuator generally has a tongue insertable into the cavity, which will urge the FPC in contact with the terminals, i.e. every one terminal in contact with every one corresponding conductive pad of the FPC.
- the electrical connection between the FPC and terminals may be failure if some conductive pads or contact portions of the terminals are polluted or oxidized.
- An object of the present invention is to provide an electrical connector providing a reliable electrical connection between the connector and a mating component, such as an FPC.
- an electrical connector comprises an insulating housing defining a cavity, a plurality of terminals arranged side by side along a lateral direction of the insulating housing.
- Each terminal comprises a contact beam with a contact portion exposed to the cavity and a solder portion extending out the insulating housing. Every at least two adjacent terminals forms a pair of terminals to transmit a same signal.
- FIG. 1 is a perspective view of an electrical connector in accordance with the present invention
- FIG. 2 is an exploded perspective view of the electrical connector shown in FIG. 1 ;
- FIG. 3 is a cross-sectional view of FIG. 1 taken along line 3 - 3 ;
- FIG. 4 is a perspective view of the terminals engaging with the FPC
- FIGS. 5 and 6 are cross-sectional views of FIG. 1 taken along line 5 - 5 , but respective showing the FPC un-completely and completely inserted into the cavity;
- FIG. 7 is a partly perspective view of the electrical connector showing the retaining tubers 16 ;
- an electrical connector 100 in accordance with the present invention is adapted for connecting an FPC 5 to a printed circuit board (PCB, not shown).
- the connector 100 comprises an insulating housing 1 , a plurality of terminals 2 retained in the housing 1 , an actuator 3 detachably assembled to the housing 1 , and a pair of locking members 4 .
- the insulating housing 1 comprises opposite walls, an upper wall 11 and an lower wall 12 thereof, and a pair of lateral wall jointing the opposite walls.
- the four walls define an FPC receiving cavity 10 and each lateral wall has a sliding channel 14 exposed outwardly to exterior and a projection 15 formed at a front end of the sliding channels 14 .
- the actuator 3 comprises an elongated base 32 defining a cutout 321 in a middle section thereof, a tongue 30 flush extending backwards from a bottom of the cutout 321 , and a pair of latching arms 31 extending backwards from two opposite end sections of the base 32 .
- Each latching arm 33 has an inwardly protruding barb (not label) at a free end thereof.
- the latching arms 3 are sliding in the sliding channels 14 .
- the actuator 3 is shifted from an open position where the latching arms 31 latch on corresponding lateral walls of the housing 1 via the engagement between the inwardly protruding barb and the projections 15 and the FPC 5 is permitted to be inserted in the cavity 10 along an inserting direction to a closed portion where the tongue 30 urges the terminals 2 to connect with the FPC 5 .
- the FPC 5 is rectangular and has a front edge which is firstly inserted into the cavity 10 .
- the FPC has a plurality of conductive pads 50 arranged side by side in a lateral direction perpendicular to the insertion direction at front portion thereof and a pair of protrusions 51 extending outward in the lateral direction from its lateral edges adjacent the front edge.
- Each conductive pad 50 includes three portions, a front portion 511 near to the front edge of the FPC and a rear portion 513 and a middle portion 512 joint the front and rear portion 511 , 513 together.
- the front and the rear portion 511 , 513 are parallel to each other and offset along the lateral direction, i.e. a width direction, so the middle portion 512 is beveled the front and rear portion.
- the housing 1 is provided with many pairs of terminal channels 13 which are communication with the cavity 10 and arranged laterally along the housing, and the distance between every pair of terminal channels 13 is shorter than that between two adjacent terminal channels 13 respectively belonging to adjacent two pairs.
- Each terminal 2 is received in the channel and comprises a contact beam 211 , 221 , a retention beam 212 , 222 and a solder portion 213 , 223 .
- the contact beam has a contact portion 210 , 220 at a front end thereof exposed to the cavity 10 for electrically contact with FPC 5 .
- the retention beam extends substantially parallel to the contact beam 211 , 221 and frictionally retained in the housing 1 .
- the solder portion extends rearward from rear ends of the retention beam 212 , 222 to connect to the PCB.
- the terminals 2 are divided into two types, the first terminals 21 and the second terminal 22 .
- the main difference between the first and second terminals is that the length of the contact beam 221 of the second terminal 22 is a little longer than that of the contact beam 211 of the first terminal 21 .
- the terminals 2 are also configured in other types according to demand.
- One first and one second terminal are inserted into one pair of channels 13 from a rear portion of the housing and forms one pair of terminals.
- all terminals are arranged alternatively along the longitudinal direction to form a member of pairs of terminals finally retained in corresponding pairs of channels 13 .
- each pair of the terminal 2 engages each corresponding conductive pad 50 .
- the contact portions 210 of the first terminals engage with the front portions of conductive pads and the contact portions 220 of the second terminals engage with the middle portions of said conductive pads.
- the solder portions of each pair are simultaneously connected with one solder pad of the PCB so that the first terminal and second terminal of each pair can transmitted the same signal.
- the contact portions 210 , 220 of each pair can electrically connect with the conductive pad 50 , and thus this configuration of the electrical connector can efficiently prevent open-circuit taking place.
- the contact portions 210 of the first terminals 21 may be engaged with the rear portions of the pads 50 .
- the bended conductive pads 50 can ensure enough engagement area of the contact portions without increasing the width of the conductive pads 5 .
- the two contact beams of said pairs may be with a same length and engage with conventional conductive pads in juxtaposition if width of pads is enough.
- Each pair of terminals also includes three terminals and more to transmit the same signal if width of the conductive pads of the FPC 5 permits.
- the locking member 4 is similar to the terminal 2 and includes a main portion 40 , a retention beam 41 extending perpendicular to the main portion 40 to be frictionally secured in the lower wall 12 of the housing 1 , and a latching beam 42 branching from retention beam 41 and extending substantially parallel to the retention beam 41 to be received in the upper wall 11 of the housing 1 .
- the latching beam 42 has a projection 44 at front end thereof for retaining in the protrusion 51 of the FPC 5 in the cavity 10 .
- the projection 44 defines a latching surface 440 perpendicular to the insertion direction of the FPC 5 , a first guiding surface 441 which is formed at an obtuse angle to the latching surface 440 for facilitating the FPC 5 being removed out of the housing 1 and a second guiding surface 442 formed at a certain angle to the first guiding surface 441 for facilitating the FPC 5 being inserted into the housing 1 .
- the housing further includes a plurality of retaining tubers 16 on the upper wall 11 of housing 1 beside the locking members 4 . Each retaining tuber 16 has a latching surface 161 which extends substantially perpendicular to the insertion direction.
- latching surfaces 161 and the latching surfaces 440 of the locking members 4 are located behind the protrusions 51 so that the FPC 5 is restricted in unexpectable movement.
- the height of latching surface 161 is configured to be not higher than that of the latching surface 440 in the latching member's 4 released position.
- the FPC 5 When the actuator 3 is in the open position, the FPC 5 is inserted into the cavity 10 along the tongue 30 , and the protrusions 51 extend beyond the latching surfaces 440 , 161 in the insertion direction. Then the actuator 3 is pushed toward to the closed position, the tongue exerts gradually enlarged force on the FPC 5 . The FPC 5 is shifted upward by the tongue 30 until the latching surfaces 440 , 161 latch on the protrusions 51 , thereby the actuator 3 is in the closed position. For defining the latching surfaces 440 , 161 , the FPC 5 is stably retained in the housing, and thus a preferable electrical connection of the electrical connector is accordingly achieved.
- the actuator 3 When the FPC 5 is required to back toward the open position, firstly the actuator 3 is moved back, that is, the tongue 30 is pulled out, thereby the FPC 5 is released downward till the protrusions 51 break off the latching surfaces 440 , 161 . Finally the FPC 5 arrives at the open position in light of the guidance of the first guiding surfaces 441 .
